Companies need to craft very enticing reasons to stay on as a 'Loser' (mostly via perks and pay) and even work harder to retain 'Clueless' since the latter is even more likely to leave and launch a startup being leadership focused. 'Sociopaths' are so few that they're easily gotten via acquisitions, or simply buy them.
Just a perspective =)
"The Gervais principle predicts the exact opposite: that the most competent ones will be promoted to middle management."
Ie, the competent losers become Clueless. Hence they're capable of jumping ship / or even starting a business if not for their 'delusional loyalty'. (My point being that lots of company brainwashing mentioned by OP attempts to groom Clueless thought patterns to prevent this flight of talent).
True that starting a company is a Sociopath trait in the writeup, but - this is far from an exact science as you correctly stated =)
(nonetheless this doc has caused many great debates over the years, for sure. Reasoning through lens of obsurdities can be fun)
If you believe that starting a company is a pure meritocracy based on how good you can build a product, you are almost by definition Clueless.
Overcoming that fear of failure and finding some Losers to help your new startup, according to the GP theory, I guess labels you as a Clueless turned Sociopath, but if you swap terms to 'Middle Manager turned CEO' I think it becomes more of an enabling perspective. (One reason I think the negative labels here can hurt folks' ambitions!!)
